side note on math facts

To go back to my post titled "my little student", I forgot to mention that Ethan only knows his +1, +0 and doubles facts for addition. We are now working on the +2 facts. So if he knew all of the addition facts, I might think he is a prodigy as well. But I think he is fairly normal in his math skills for his age. Anyway just felt like I needed to say that with the responses I got from a few readers.
